COMPUTER MAINTENANCE

Computer maintenance is the process or practice of keeping the computer in good working condition.

A computer system consists of both hardware and software.

The hardware components of a computer are the electronic and mechanical parts of a computer, mostly called the physical parts of the computer while the software components of a computer are programs stored on the hardware.

 Hardware maintenance

This involves taking care of the computer’s physical components such as the computer keyboard, monitor, hard drive, mouse and other peripherals. 

Importance of Hardware Maintenance

1. It helps to extend the computer’s lifespan
2. It helps to prevent wear and tears
3. It helps in keeping the smooth functioning of the system 

Physical maintenance on a computer system

1. Keep the computer away from dust and dirt.
2. Keep liquids away from the computer
3. Use surge protector
4. Use Uninterrupted Power Supply (UPS)
5. Clean the monitor with a slightly dampened clean cloth
6. Use Laser lens cleaner to clean the DVD/CD lens
7. Keep your crumb-free
